When I used to press Tab button in command prompt, the names of available files in that directory pops up.
But I updated win10 with KB4458469 last night and this function is not working.

This issue can occur if the completion function is disabled in the registry. This can happen after installing new Windows updates which may have disabled the feature.

In this article, we show how to fix Windows 10 command prompt autocomplete not working problem.
